## Description

10-18mm F2.8 DC DN for RF Mount

Review: Nice Lens- Just What I needed - This review is my first impressions of the lens. I haven't spent a lot of time with it yet, so if my opinion changes, I will come back and update this review. To begin with, I was really happy to find this lens. I got a Canon R7 a few months ago along with the RF 100-400mm lens as I do a lot of birding and wanted a lighter-weight rig for the field than my 6D with EF 100-400mm lens. However, I also like to do landscape and travel photography when on vacation and the occasional milky way or aurora astrophotography shot. The 1.6x crop factor of the R7 makes it really hard to get wide landscape shots. Through an adapter, I tried my 17-40 lens on it that is my go-to for landscapes on the 6D and it was nowhere near wide enough. I needed to be much wider than 16mm on the R7 to get the shots I wanted. I thought the Canon RF-S 10-18mm f4.5-6.3 was my only option and was ready to buy it when I saw the announcement that Sigma was coming out with an f2.8 version. Fantastic! That f2.8 will make a huge difference for astrophotography. I watched it for a while and pulled the trigger on a used one on desertcart from Gabrians (Note the price was good at $549 but the shipping was ridiculously slow- ordered Nov. 29th, arrived Dec. 13th. It was also sent signature required but didn't indicate this anywhere, so I had to arrange a trip to the post office to pick it up the next day as I was not around to sign for it). The lens itself is a nice size and weight. It comes with a small lens hood. I screwed on a UV filter / lens protector immediately and took some test shots. There didn't seem to be significant vignetting with the filter on, which was a pleasant surprise. I was expecting a lot of drop-off at the corners based on other wide angle lenses I have used, but it wasn't noticeable. Even if it was, RAW converters are excellent at fixing that automatically anyway. Focusing is very fast and quiet. So quiet, in fact, that I can't even hear it. I don't particularly like the zoom ring however. Everything about it is backwards from every other lens I have used. It is the further ring from the body, not the closer one, unlike just about every other lens I have. Second, the rotation is the opposite direction of every other lens I have. You rotate it counter-clockwise to zoom in and clockwise to zoom out. That's really the only complaint I have about this lens. The manual focus / multi-function ring works as expected and manual focus override works well with the R7. The lack of image stabilization in the lens isn't a problem since the R7 has in-body stabilization. In my limited testing, the photos came out sharp and I didn't notice any chromatic aberration problems. Close focus is very close. At 10mm it can focus on something pressed right up to the edge of the lens hood. Overall, I give this lens 5 stars for now as it seems like a good lens and fills an immediate need for a fast, ultra-wide angle for crop sensor RF cameras. About the only thing missing from it that I would like is weather sealing for peace of mind.
Review: Great for almost everything… - I’ve owned this lens for quite a couple months now and it’s served me well for the most part! I use it on my canon R8 where the camera automatically crops in to a 1.6 and makes the focal length just a slight bit tighter. It’s perfect for the price point where most native lens for canon are tripled for the same use!! Super light weight and sometimes can’t tell it’s on my camera lol! The build quality is nice and smooth on the zoom, I like the added ring for certain controls but don’t usually use it and is very smooth to mount. It’s got great focusing on photos and videos you never hear a single thing move in the lens so for those shooting video it’s great! I’ve used it so far for single portraits, group photos and videos for small businesses and products all with very good ease of use.
